When using digital microscopes , people often don't know how to accurately calculate the actual magnification of a digital microscope . In fact, this problem is very simple and can be solved perfectly with only one formula.
Ok, here's how to accurately calculate the actual magnification of a digital microscope :
Because the imaging system used in digital microscopes is a microscope CCD camera and a microscope CMOS camera, you must first understand the dimensions of these two types of microscope cameras: 1 , 2/3 , 1/2 , 1/3 , 1/4 inch.
Traditional two-dimensional stereo, biological or gold equivalent microscope, the implementation method:
Digital microscopes are generally implemented using a third mesh plus a microscope CCD camera and a microscope CMOS camera. The traditional two-objective stereoscopic optical microscopy is achieved through some modifications. We should know that the CCD or CMOS target size is closely related to the magnification, and its size is directly related to the magnification of the digital microscope.
Target size:
The target size in the usual sense is the actual size of the CCD or CMOS as follows:
1 inch - the target size is 12.7 mm wide by 9.6 mm high and the diagonal length is 16 mm ;
2/3 inch - the target size is 8.8 mm wide x 6.6 mm high, and the diagonal length is 11 mm ;
1/2 inch - the target size is 6.4mm wide x 4.8mm high, and the diagonal length is 8mm ;
1/3 inch - the target size is 4.8mm wide x 3.6mm high, and the diagonal length is 6mm ;
1/4 inch - the target size is 3.2 mm wide by 2.4 mm high and the diagonal length is 4 mm .
Now that we know the target size of a CCD or CMOS , it is easy to know what the digital microscope magnification is. The specific calculation formula is as follows:
Magnification of the objective lens × ( diagonal of the computer screen / target size of the CCD or CMOS ) = total magnification.
The above method is not very simple!
